    GeoLock Technology GeoLock™ technology is a feature of the Spectra Precision Survey Pro software that allows a robotic total station to perform an aided search for an optical target using an initial GPS position. The technology greatly reduces the time to locate and lock onto a target.

  • Page 82: Robotic Measurement

    5 – Instrument Operation Methods The Spectra Precision GeoLock technique combines a GNSS position with the FOCUS 35 robotic total station and the robotic roving operator. The remote instrument can then be directed towards the robotic roving operator using the GNSS position and a subsequent search is quickly performed to reacquire the target at the robotic rover.

    Correction for Trunnion Axis, page Correction for Mislevelment The Spectra Precision FOCUS 35 Total Station automatically corrects for mislevelments up to ±5.5’. The instrument warns the operator immediately of any mislevelments in excess of ±5.5’(±0.1 grads). Corrections for the horizontal angle, vertical angle, and slope distance are calculated in the field application software and applied to all measurements.

  • Page 85: Correction For Collimation Errors

    Spectra Precision FOCUS 35 Total Station with LockNGo Tracker A Spectra Precision FOCUS 35 Total Station with LockNGo capability can automatically lock and track a prism target as it moves. Pointing errors caused by slight misalignment of the instrument’s tracker have a similar effect to the HA and VA Collimation errors as detailed above.

  • Page 86: Correction For Trunnion Axis

    Trunnion axis tilt error In the Spectra Precision FOCUS 35 Total Station, perform a pre-measurement trunnion axis tilt test to determine the trunnion axis tilt error. Angular measurements are observed in both instrument faces, the trunnion axis tilt error is calculated, and the respective correction value is stored in the instrument.

  • Page 87: Averaging Measurements To Reduce Sighting Errors

    • Distance Measuring Technology Spectra Precision FOCUS 35 Total Stations are equipped with a combined distance unit. This means that the instrument can measure to a prism or to normal surfaces (reflectorless mode). The laser distance unit is based on the phase comparison method. The distance unit is coaxial with the line of sight and transmits an intensity modulated optical measuring beam that is reflected by a prism or scattered by a natural surface on which the beam is directed.

  • Page 88: Beam Divergence

    A smaller measuring area has advantages when measuring tight corners and vertices at close range. When observing measurements to a tight corner, the distance meter beam divergence introduces a range error caused by the size of the sampling area. FOCUS 35 TOTAL STATION USER GUIDE...
